Xinmin Evening News (Reporter Ma Dan) The old saying goes: when the cathode arrives, the yang begins to grow, the sun reaches the south, when the day is short, and when the shadow is long, it is called “winter solstice.” When the sun was hiding in the embrace of the night, the days in the northern hemisphere were the shortest and the night was longest. Today we finally mark the beginning of the oldest of the twenty-four solar terms: the winter solstice. At the same time, the “number of nine” began. Although the days have increased day by day, the city of Shanghai, which has entered winter, will receive the coldest time of the year.

Ancient China attached great importance to the solar terms of the winter solstice, and the “winter solstice” was also called “Ya Sui”. Already in the spring and autumn period more than 2,500 years ago, China had used Tugui to observe the sun and determine the winter solstice. Not only was it one of the first determined solar terms, it was also ranked first among the 24 solar terms. People also have “the winter solstice as big as the new year.” One is that the new year is approaching and there are not many days left. The other is that the importance of the winter solstice is second only to the new year. There is a saying in the verse that describes Shanghai in the old days: “Every family pounds rice to make glutinous rice balls, knowing that it is the winter solstice of the Ming dynasty.” The people of Shanghai are used to eating glutinous rice balls on the winter solstice to celebrate the arrival of the solar term.

The arrival of the winter solstice means that “counting nine cold days” has begun. However, at this time, the heat stored in the ground has not dissipated to the extreme. Then, as the heat subsides and the cold air is active, the temperature will continue to drop. Therefore, there is a saying that “the number of cold days is nine, the cold is thirty-nine”. However, for Shanghai, March 9 may not be the coldest time of the year. Shanghai’s coldest one-year period usually occurs at the end of January, and in some years, the coldest period also occurs at the beginning of February. Therefore, generally speaking, Shanghai’s “Forty Nine” will be colder than “Three Nine”.

Winter Solstice

In “Yue Ling 72 Hou Ji Jie” of the Yuan Wu Cheng dynasty, it was recorded: “Winter solstice, mid-November. The final deposit of Qi, until now.

In ancient times, the winter solstice in the twenty-four solar terms was divided into three phases:

“One-time worm knot”, the earthworm is said to be a creature that stretches yin and yang. Although the yang qi has grown at this time, the yin qi is still very strong and the earthworms on the ground are still huddled;

“Second term Mi horns solution”, Mi and deer belong to the same family, but yin and yang are different. The ancients believed that the horns of Mi were yin, and when the horns of Mi were yin, when yang was born on the winter solstice, Mi felt the yin qi gradually recede and lighten the horns;

“Three-period water spring movement” means that the spring water in the mountain can flow and be hot right now due to the new generation of Yang Qi.
